Biggest xl 1.6 x 1.5 x 1.6 cm, own find, 4th mindat conference.
Found during the 2016 Mindat conference: pyrite crystals pseudomorphed or covered by goethite (I did not break any of my finds open to see if there is pyrite left). Forms are mostly cubes but also modified by the pentagondodecahedron (pyritohedron). Sometimes clusters. These are three examples which were typical for the finds that could be made in Nov. 2016.
